Cancer Cytotoxic Exosome Formulations and Methods for Use in Treating Cancer

By using metal sulfides (e.g., FeS2, CuS, CuS, and CuS) to adsorb and convert Hg0 from β-glucan-stimulated exosomes from human or animal cells, the challenges of existing technologies are addressed, achieving efficient and cost-effective mercury removal.

Abstract

Compositions and methods for treating cancer, particularly leukemia, using a cytotoxic composition comprising monocytes activated by-glucan. The monocytes are preferably incubated with the β-glucan and then processed to extract particles, such as microvesicles and exosomes from the treated monocytes to produce the cytotoxic composition. Preferably the cytotoxic composition comprises at least 50% exosomes having a size of 150 nm or less that are activated with β-glucan. Zymosan is the preferred β-glucan. The cytotoxic composition has an apoptosis effect. When a subject having cancer is treated according to preferred embodiments, the cytotoxic composition preferably induces a cytokine response in the subject's immune system. The combination of the cytotoxic composition and cytokine response are synergistic.
